This is called "ramping it up." Again, the mature thing, for me at least, and most people I know, would be to chalk it up as an error (for the server and for the water bottle thrower) and not compound the problem by escalating it. I think forgiving and asking for an apology is the thing to have done. But heck, I live in the *******, and not crazy land.

Just call the police right away and file a report. That is the best way to handle things.
